George Karl might miss rest of regular season

DENVER (AP) -- The Denver Nuggets might not have coach George Karl back on the sideline until the playoffs begin next month.

Karl is undergoing treatment for throat and neck cancer and, according to a blog by his girlfriend, he was hospitalized this week with blood clots in his lungs and a leg.

Adrian Dantley has served as acting head coach for eight games since Karl announced just after the All-Star break that he had been diagnosed with cancer. Dantley is 5-3 in those games.

The Nuggets (47-24) are tied with Dallas in second place in the Western Conference standings and are clinging to a one-game lead over the Utah Jazz in the Northwest Division. They've lost two straight games, at home against Milwaukee, and at New York on Tuesday night, which kicked off a crucial five-game trip.

Karl, who beat prostate cancer a few years ago, is undergoing radiation and chemotherapy treatment and has missed the Nuggets' last three games. He did not accompany his team on its trip out East.

Karl's partner, Kim Van Deraa, wrote on her blog that Karl had to be rushed to the hospital on Sunday afternoon because he had difficulty breathing and one of his legs was extremely swollen. She wrote that he was diagnosed with blood clots in his lungs and leg and that he underwent a procedure to place a filter in his stomach that would catch any blood clots.

Karl was much improved by Monday night, Van Deraa wrote. She said, however, that they weren't sure when he would be released or when his radiation treatment would continue.

"We're hoping both occur -- since it would mean he's gotten through the scare of the blood clots and we don't want to add any weeks onto the schedule of radiation," Van Deraa wrote in her blog, which was first cited by the Denver Post.

The Nuggets return from their trip on March 30 and play four of their last six games at home. Their regular season ends April 13.

The Nuggets also hope to have defensive stalwart Kenyon Martin back in mid-April in time for the playoffs. Martin has been sidelined by patella tendinitis in his left knee and underwent a dose of platelet-rich plasma therapy recently.

He will meet with doctors next week at the Steadman Hawkins Clinic in Vail to see if he needs another dose that could delay his return to the basketball court.
